Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to an apparatus for cutting and removing unnecessary objects attached to various castings such as automobile parts obtained by casting aluminum or the like, and in particular, to a diamond tip saw for cutting and removing unnecessary objects such as gates of castings. This system is used for cutting and removing unnecessary objects from castings, which is equipped with a rotating device such as a motor that rotates the tip saw at high speed.Specifically, it reduces the amount of diamond chips used, achieves energy saving in cutting power, and performs cutting. The present invention relates to an apparatus for cutting and removing unnecessary substances attached to a casting, which reduces chips generated at the time of the casting, thereby reducing waste of the material of the casting, thereby greatly reducing the production cost of the casting.

[0002]

[Prior art]

 Various automotive parts, such as cylinder heads, cylinder blocks, and intake manifolds, are manufactured by casting aluminum. Since the casting obtained by this casting has an unnecessary material such as a gate, it is necessary to cut and remove the unnecessary material from the casting.

[0003] As this kind of unnecessary object cutting and removing apparatus, a diamond tip saw is conventionally mounted on the tip of a rotating shaft of a rotating device such as a motor, and the rotating device drives the diamond tip saw at a high speed to rotate the diamond tip saw. Unnecessary castings were cut off by force.

[0004]

[Issues to be solved by the invention]

 At this time, the rotation speed of the diamond tip saw is 1000 rpm to 1800 rpm. In order to prevent the occurrence of vibration during cutting, for example, when the diameter of the tip saw is about 400 φ, the thickness of the tip saw needs to be about 6 to 8 mm. Further, in the past, if the rotational speed of the diamond tip saw was increased any further, the cut pieces were scattered at a high speed to damage the tip saw, and the noise became extremely loud.

When the inventor increases the rotation speed of the tip saw to 3000 rpm or more, the rigidity of the tip saw is significantly improved by the centrifugal force and the gyro moment effect of the tip saw itself, and as a result, the thickness of the tip saw is increased by the rigidity of the tip saw. It was discovered that it was possible to reduce the thickness, and the present invention was completed.

[0006] An object of the present invention is to provide an apparatus for cutting and removing unnecessary objects from a casting, comprising a diamond tip saw for cutting and removing unnecessary objects such as a gate of a casting, and a rotating device such as a motor for rotating the tip saw at high speed. In addition to reducing the amount of diamond chips used, achieving energy savings in cutting power and reducing chips generated during cutting, waste of casting material is reduced, thereby reducing the cost of producing castings. It is an object of the present invention to provide an apparatus for cutting and removing wastes attached to a casting, which significantly reduces the disadvantages of the above-mentioned prior art.

[0007]

[Means for Solving the Problems]

 In order to achieve the above object, according to the present invention, there is provided a device for cutting and removing unnecessary matter attached to a casting, which has a rotating shaft and rotates the rotating shaft at high speed; A disk-shaped diamond tip saw that is attached to the tip and is rotated at a high speed by the rotation of the rotating shaft to cut and remove unnecessary material from the casting is provided. The tip saw is rotated at a high speed of 3000 rpm or more, and the high-speed rotation is performed. Due to the centrifugal force and gyro moment effect of the diamond tip saw itself, the rigidity of the tip saw is improved, and the thickness of the tip saw can be reduced by the increased rigidity of the tip saw, thereby reducing the amount of diamond tip used. It is characterized by energy saving of cutting power and reduction of chips generated during cutting.

[0008]

[Embodiment of the invention]

 Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a perspective view of a specific example of the cutting and removing apparatus according to the present invention, and FIG. 2 is an enlarged partial side view of a portion a of FIG.

In FIG. 1, reference numeral A denotes a cutting and removing apparatus according to the present invention, which includes a rotating device 1 such as a motor and a disc-shaped diamond tip saw 2. The motor 1 (rotating device 1) has a rotating shaft 3, and a tip 4 of the rotating shaft 3 is mounted with a disc-shaped diamond tipsaw 2. Then, the rotating shaft 3 of the motor 1 is rotated at a high speed by the driving of the motor 1, and with this rotation, the disk-shaped diamond tip saw 2 mounted on the tip 4 is also rotated at a high speed.

As shown in FIG. 2, which is an enlarged side view of the portion “a” in FIG. 1, the periphery of the chip saw base material 5 has a large number of chips 6, 6,. 6 and diamond tips 7, 7,... 7 are attached to these tips 6, 6,. The size of the diamond blades 7 is, for example, 4 mm × 4 mm × 1 mm, and is attached to the super hard material 10.

The diamond tip saw 2 is rotated at a rotation speed of 3000 rpm or more, preferably 3000 rpm to 3600 rpm by the rotation of the rotating shaft 3 by the motor 1, and as shown in FIG. At this time, for example, the unnecessary material 9 attached to the cylinder head casting 8, which is an engine part of an automobile, is cut and removed.

The rigidity of the tip saw 2 is remarkably improved due to the centrifugal force and the gyro moment effect of the diamond tip saw 2 rotated at a high speed, and the thickness of the tip saw can be reduced by the increased rigidity of the tip saw. In other words, in the prior art having a tip saw size of about 400 φ and a cutting spindle rotation speed of 1800 rpm, a tip saw thickness of about 6 mm to 8 mm was required, but in the present invention, the cutting spindle rotation speed was 3600 rpm. When cutting a gate with a cutting area of 50 mm × 100 mm at a feed rate of 30 mm / sec, the thickness of the tip saw can be 4 mm.

As described above, by reducing the thickness of the tip saw from 6 mm to 8 mm to 4 mm, the amount of diamond tip used is reduced to, for example, 4 mm × 4 mm × 1 mm, and the cutting power, that is, the motor 1 shown in FIG. Energy of the cutting power is achieved, and chips generated from the joint portion 11 generated when cutting the waste 9 of the casting 8 are reduced, which can greatly contribute to a reduction in production cost of the casting. . In FIG. 1, reference numeral 12 denotes a clamp for holding the casting 8 therebetween, and is fixed to the support plate 13. The clamp 12 is also attached to a support plate 13 at an opposing position (not shown), and holds the casting 8 from both sides.

[0015]

[Effect of the invention]

 As described above, in the present invention, when the rotational speed of the diamond tip saw is increased to 3000 rpm or more, the rigidity of the tip saw is significantly improved due to the centrifugal force and the gyro moment effect of the tip saw itself. The thickness of the tip saw can be reduced, for example, from 6 mm to 8 mm to 4 mm, and the cost can be reduced. This is a very useful device in practical use.
